The ceiling of a building is 14.5m above the floor below. A girl hits a ball straight up and it just barely hit the ceiling. If her shoulders are 1.75m above the ground and she hit the ball at shoulder height, what was the [vector] velocity of the ball just after it was hit? Air resistance can be ignored

From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...
